3 Claims.

My invention relates to attachments for cultivators and the like, andmore particularly to a means for adjustably supporting a pair of sweepsin operative relation with a plow which is carried on the standard of acultivator.

The object of this invention is to provide a compact, simple andinexpensive attachment for cultivators which is adapted to swinginglyadjustably support a pair of sweeps which will coact with a cultivatorplow for conditioning the soil without hindrance to the plant.

An advantage of this invention is that a one row cultivator may beconverted into a two row cultivator by adjusting the sweeps in properrelation with the cultivator plow.

Another advantage of this invention is that the structure is light anddurable and may be adjusted with a minimum amount of effort.

Another advantage of this attachment is that it will function to securea loose mulch of the surface of the soil.

Other objects and advantages will be fully eX- plained in the followingdescription and the invention will be more particularly pointed out inthe claims.

Reference is had to the accompanying drawing which forms a part of thisapplication.

Fig. l is a side elevation of the device, shown attached to theconventional cultivator standard.

Fig. 2 is a plan View of the same.

Fig. 3 is a rear view of the same.

Fig. 4 is a rear view of the device, showing a variation in thestructure thereof.

Fig. 5 is a front elevation of the device.

6 is a detail View of the device, shown with one of the sweeps removed.

Fig. 7 is a detail view of one of the sweeps and means for adjustablyattaching the same to one of the swinging members.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The device consists of a ring type structure which is adapted to encasethe lower end of a cultivator standard and support a pair of sweeps l inoperative relation with the cultivator plow. The ring structure isformed in three segments. One of the ring segmentsl is formed so as torest upon and conform to the leading surface of the standard 2 of acultivator; The shank of the cultivator plow 3 is placed upon thesegment l and these are held in a rigid manner by means or" a pair ofbolts 4. The segment i is interposed between the leading edge of thestandard 2 and the plow 3 and the bolts are passed through the shank ofthe plow; the segment I and the standard 2.

The other two segments of the three piece ring structure are eachpivotally connected one to each edge of the segment I by means of apivotal pin 5. These segments 6 are adapted to normally swing rcarwardlyrelative to the standard 2 and encase the same. The outer periphery ofthe two segments 6 of the ring structure are provided with a pluralityof openings 7 which are formed to receive and adjustably hold blade typevanes or sweeps 8. The holes I are radially disposed in the segments 6so that the sweeps 8 may be carried at various angles relative to theplow 3 of the cultivator. Each segment 6 of the ring structure isadapted to support one sweep 8.

The sweeps 8 are each formed of a relatively long piece of thin metalhaving the opposite longitudinal edges sharpened so as to engage thesoil and serve as a plow or hoe. One end of the sweep B is adapted toproject into a slot formed in the end of a shaft 9. Bolts H! are passedthrough the shaft 9 and through the sweep 8 for removably holding thetwo together. The end of the shaft, opposite the sweep 8, is extendedand provided with an annular groove H. grooved portion of the shaft 9 isadapted to project into the openings 1 which are provided in theswinging sections 6 of the ring structure. The sweeps B are held intheir respective swinging sections 5 of the ring by means of a pin [2 orset-screw which passes through the ring section and into the groove IIof the shaft 9. The valley of the annular groove H is provided withindentations for the reception of the set-screw l2 in order to insurethe rigidity of the vane with the ring when the vane or sweep 8 isadjusted to the desired slant relative to the horizontal. In thisinstance, the two swinging portions of the split collar are eachprovided with three openings '5. When the sweep 8 is adjustablypositioned in the opening 1, adjacent the plow 3, it will cooperate withthe other sweep to span the maximum width of cultivating the soil. Whenthe operator desires to cultivate a smaller strip of land, he may movethe sweeps 8 to either of the rear openings I provided in the collarportions 6.

The segmental ring which is adapted to be secured to the standard 2 of acultivator is formed so that its axis will be in a vertical plane. Thisposition of the ring requires that the portion I of the ring bepositioned at an angle to the sectors E of the ring. The portion I ofthe ring is set an angle to conform with the angle of the conventionalcultivator standard 2. The standard This sectors 6 will be forced toswing to the rear of.

the cultivator standard 2 and encase the same. Thefree ends of thesectors 6 will, in this instance, be forced against each other in amanner so as to serve as a brace for the unit embracing the standard 2.In some instances, one of the sweeps may be forced against rocks or astump in a field and break one of the sectors 6 of the unit. If thisshould happen the operator may repair the device without removing thewhole unit from the standard 2 which would be a loss of time andexpensive. The swing of the members 6 permits the operator to have easeof access to adjustment of the sweeps 8 and also access to the lowerbolts holding the member I rigid with the cultivator standard 2.

What I claim is:

1. An attachment for cultivators and the like consisting of a collarformed into three sections, one of said sections being rigidly attachedto the standard of a cultivator, each of the other two sections of saidcollar being pivotally connected to the said first named section andadapted to encase said standard, and means for adjustably securingsweeps in various portions of the outer periphery of each of saidpivotally connected sections of said collar.

2. An attachment for cultivators and the like consisting of a circularmember formed in three sections, one of said sections being rigidlyattached to the standard of a cultivator and adapted to operativelysupport a plow, the other two sections of said member being eachpivotally connected to said first named section, the free ends of saidlast named sections being provided with means for aligning said endswith each other when the same are brought around said standard and intoengagement with each other, and means provided in the outer periphery ofsaid last named sections for adjustably supporting sweeps in operativerelation with said plow.

3. An attachment for cultivators and the like consisting of an elongatedmember rigidly attached to the front of the standard of a cultivator, apair of are shaped members pivotally attached one to each side of saidelongated member, said pivoted members being adapted to swing aroundsaid standard whereby their free ends may engage and support each other,and radial openings disposed in said pivoted members for adjustablyholding ground sweeps relative to said standard.
